Every year, after the harvest and when people's lives are stable, the Co Tu ethnic group in A Luoi district joyfully prepares for the Tac Ka Coong festival, a sacred and special traditional festival. This is not only an occasion for the Co Tu people to express gratitude to nature and the gods but also an opportunity for the community to unite and affirm their cultural identity.

In Doi village (Thuong Lo Commune, Nam Dong District), there is a special man who quietly and diligently preserves and promotes the traditional values of the Cơ Tu ethnic group. This man is Pơloong Chướch, a senior artisan who has dedicated his entire life to the craft of weaving.

Quynh Teu, a man of the Co Tu ethnic group, who had contributed a lot to the revolution against the Americans in the mountainous area of Nam Dong, considered the silver bangle, the handkerchiefs, and the aluminum mug presented to him by Uncle Ho a treasure which should be cherished and well protected for his descendants.

The New Rice Festival is a very important ritual in the life of the Cơ Tu ethnic group in Nam Dong district. The festival shows respect to the gods for blessing the village with a stable life, favorable weather, and bumper crops.
